Specification of Letters Patent.

Eatented Apr. 18, 1911.

Application `filed December 2, 1909. lSerial No. 530,959.

To all 'whom it 'may concern:

Be it known that l, GEORGE I. KING, a citizen of the United States,residing at Middletown, Pennsylvania, have invented a certain new anduseful Improvement in Car- Underframes, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, Aformingppart of thisspecification, in which- Figure l is an elevation of the end portion ofone ofthe open web fish belly sills made use of in my improvedunderframe; Fig. 2 is a fragmentary cross section of a gondola having anunderframe of my improved construction; Fig. 3 is an elevation of theend portion of a modied form of the open web sill; Fig. 4 is a sectionsimilar to Fig. 2, and showing the form of underframe used in connectionwith a flat car.

My invention relates generally to car'u'nderframes, and moreparticularly to the sills thereof, the principal object of my inventionbeing to construct an open web sill, the central portion of which isextended downward in fish belly form, and which type of sill whileespecially applicable for use on comparatively light weight cars, can beadvantageously used with any kind of superstructure, or with any type oftrucks.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts hereinafter more fullydescribed and claimed.

My improved underframe as shown, is preferably made up of a pairofcenter sills, and a pair of side sills, all of which sills are alikein construction. Each sill comprises a compression member l, preferablyin the form of a commercially rolled angle, and which is continuous fromone end of the frame to the other.

The lower tension member 2 of the sill, is preferably in the form of acommercially rolled angle, the central portion of which is arranged asuitable distance below the upper member l, and the end portions of saidmember 2 are bent upward on inclined lines as designated by 3. Theextreme outer end portions of the tension member are xed to the endportions of the compression membraces 6.

ber l by means of rivets, or in any suitable manner.

Arranged between the members l and 2 adjacent the point where the member2 is bent upward to meet said member 1, are spacing plates l, preferablyformed of pressed steel, and the ends of these plates are rigidly fixedto the members l and 2 by means of the rivets, or in any suitablemanner. Each'plate is preferably provided with a centrally arrangedvertically disposed strengthening rib 5, which is pressed from thematerial of which said plate is formed. Arranged between the members lof each corresponding pair of center and side sills, are transverselydisposed floor braces Y6, of

Aany suitable construction, and the ends of said braces are fixed to themember l in any suitable manner. Uniting the member 2 of eachcorresponding pair of center and side sills, are transversely disposedtie-plates 7 of anysuitable form, and preferably providedwithlongitudinally disposed strengthening `ribs such as 8'. Thus each pairof center and side sills are united by braces and tie-plates, and theupper portion of the frame so formed, is further strengthened and bracedby floor sheets 9, which are laid directly upon the member l, and thefloor Arranged above t-he space between the pair of center sills is afloor plate 10, the edges of which are fixed in any suitable manner tothe members l of the center sill. Vhere my improved underframe isutilized in connection with gondolas, a stake 1l preferably in the formof a channel is rigidly fixed to the inner faces of each spacing plate4, and these stakes extend a sufiicient distance above the fioor sheetsto accommodate the plates or timbers forming the side walls of thegondola. Intermediate stakes for supporting the side walls can beriveted to the upper member 1 of the side sills.

It will be noted that the horizontal legs of the angles forming thecompression and tension members of the sills, utilized in theunderframefor gondolas, project outward away from the longitudinalcenter of the frame, but where an underframe is constructed for a fiatcar as shown in Fig. 4, the compression and tension members of the sillsare arranged so that their horizontal flanges project inward, and stakepockets 12 of suitableV construction, are riveted to open web fish bellysillsare made use of, and

the outer faces of the vertical legs of the u and rigidity with minimumweight, and can compression members 1. One of these stake pockets 1sarranged on the member 1, d1- rectly opposite each spacing plate 4, and

thus the lower portion of the stakes arranged in these pockets, can beextended downward, and have an eXtra long bearing against the spacingplates, the said stakes resting in th recesses formed by thestrengthening ri s 5.

Where the strut has its vertically disposed pocket facing inwardly asshown in Fig. 1, the parts in alinement with the pocket may be cut awayso that the stake may be fitted in the pocket; and when the pocket facesoutwardly as shown in Fig. 4, the usual stake pocket 12 may be securedto the upper end of the strut to receive the stake, whose lower end fitsinto the vertically disposed outwardly opening pocket of the strut,holding the strut rigidly in its vertical position.

In some instances, I may find it desirable to unite the ends of themembers 1 and 2 by means of a riveted plate as shown in Fig. 3 insteadof riveting the ends of said members directly together as shown in Fig.1.

Thus it will be seen how I have provided an improved underframe forcars, wherein which underframe combines great strength be cheaplyproduced by reason of theuse of plain structural shapes and plates only,and Said frames being particularly desirable in the manufacture ofcomparatively light weight fiat, boX and gondola cars.

I claim: v

1. A. longitudinal trussed sill for car frames, the strut of which is inthe form of a plate embossed to form a mid-rib and to provide avertically disposed pocket.

2. In a car frame, two parallel trussed longitudinal sills connectedtogether at their upper and lower edges, a pair of said connected sillsbeing arranged at each side of the car, and being connected together attheir upper edges only.

3. A strut for a longitudinal car sill having a vertically embossedmid-rib forming a pocket, and a stake in said pocket.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses, this 241th day of November, 1909.l
